Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When you’re looking into an air conditioner replacement, you’ll find that the HVAC industry is filled to the brim with acronyms and perplexing terms. You’ll want to get acquainted with a few of these acronyms and other common terms to be able to successfully research your purchase—particularly the terms that help interpret energy efficiency. Let’s learn some of these terms. What is EER? EER stands for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain level. Look for higher ratings on this one because the higher the EER rating is, the more energy efficient the model is. You could be seeing lower utility bills in no time. ENERGY STAR® Certification You’re most likely familiar with ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was started in 1992 by the U.S. Environmental Protection Agency. The goal was to protect the environment while helping consumers save money on energy by using more energy-efficient products. Products must undergo rigorous third-party testing and meet all of the requirements to become ENERGY STAR certified. So, when you see the blue ENERGY STAR label while you’re shopping for an air conditioner replacement, you’ll be certain it will save you money. ENERGY STAR - Most Efficient The ENERGY STAR Most Efficient designation recognizes the products with the greatest efficiency among those that are ENERGY STAR certified. These exceptional products represent the leading edge in energy efficient products every year. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio (SEER) is the degree of your air conditioner’s or heat pump’s cooling efficiency. The major difference between SEER ratings and EER ratings is that SEER is a measurement of an air conditioner’s efficiency over the entire cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency equates to more money savings and a decreased impact on the environment. If you have an older air conditioner, the SEER rating could be as low as 8, while recent, more efficient models range from ratings of 13 – 23. Of course you’ll find more acronyms and unfamiliar terms when you are looking into your air conditioner replacement, but you’ll be more prepared by knowing these terms.
